My dog used to have separation anxiety every time I left the house. I tried to find things to distract her when I left, but nothing kept her attention long enough for me to get out of the house. I stuff treats in this ball and she keeps focused and gets all of the treats out. Perfect solution to keep her occupied as I leave for work. Very easy to put treats in and I’ve had it for about 6 months now, which is great because my dog chews toys to pieces within days! High quality ball. I love it so much (well, my dog loves it so much), I bought one to give my neighbor’s dog.

Good toy, wish it was slightly bigger

Size: 2.8in for Small & Medium Dogs, Size: 2.8in for Small & Medium Dogs

I got the medium to large size ball for my elderly boxer who has suddenly taken to chewing on everything. The toy has been a decent purchase. Pros: not incredibly stiff plastic for elderly dogs. Easy to manipulate to put treats in the spikes. Easy to clean. Seems engaging for my dog. Cons: probably not for super chewers. This size is probably too small for large or extra large dogs. My dog can easily fit this in his mouth and I wish it was just a little bigger. The ball can only hold one mini milk bone per slot, so it makes for treats to be really easily pulled out. Can't comment on durability yet, haven't had it for long enough. Overall, I like this toy. I just wish it was slightly wider or bigger.

Durable, Fun, Useful!

Size: 1.8in for Puppy Dogs

This treat dispenser is so great! For one thing, it's sturdy and will last forever. It will get lost before it wears out. This is my second order because I can't find the first one . . . so I bought this pack of two. In one, I put peanut butter. In the second one, I put toothpaste, just a squirt for each opening. My dog LOVES to chew on this even after she has consumed 98% of whatever I put in there. In short, it occupies her attention, which is a blessing! It's both a treat and a toy. It also bounces well and can be thrown as a ball. It will LAST far longer than any ofher other balls, too. My dog has a tiny mouth and larger balls are too big or too hard for her. If I could give it more stars, I would!
